  "textContent": "Provided is an integrated circuit for light reception 1 which can be used in both a light quantity detection type photoelectric sensor and a distance setting type photoelectric sensor. The integrated circuit for light reception 1 includes: a pair of light receiving amount signal input parts (for example, terminals 10A and 10B) that externally takes in a light receiving amount signal; an amplifier circuit 100 that includes a function of amplifying a single light receiving amount signal, a function of summing up and amplifying a pair of light receiving amount signals, and a function of differentially amplifying a pair of light receiving amount signals; a setting signal input part (for example, a terminal 105) inputting a setting signal in order to enable one of the three functions of the amplifier circuit 100; a switching processor 10 that relays the light receiving amount signal or signals of an amplification target or amplification targets to the amplifier circuit 100; a signal processor 16 that controls an operation of the switching processor 10 in accordance with the setting signal input from the setting signal input part such that the switching processor relays the light receiving amount signal or signals, which is or are to be amplified by the function enabled by the setting signal, the signal processor 16 performing signal processing to the post amplification signal based on an operation definition determined by the enabled function; and an output part 18 that outputs a signal representing a processing result of the signal processor 16.",
